Abstract

본 발명은 공정 온도가 금의 용융점 미만인, 실질적으로 완전히 조밀화된 미분쇄 금 입자의 제조 방법에 관한 것이다. 금 함유 화합물 불포화 용액으로 된 에어로졸 중 미분 액적의 농도를 적절히 조절함으로써 순도가 높고 원형이며, 실질적으로 완전히 조밀화된 입도 분포가 제어된 미분쇄 금 입자를 제조할 수 있다.The present invention relates to a process for the preparation of substantially fully densified finely ground gold particles wherein the process temperature is below the melting point of gold. It is possible to produce finely pulverized gold particles whose purity is high, circular, and substantially completely densified and whose particle size distribution is controlled by appropriately controlling the concentration of the fine particle droplets in the aerosol comprising the gold-containing compound unsaturated solution.
